And yes it was quite the PITA. Pass side took about 1.5 hours. Got #2, 4, and 6 from the top after removing the AIR tube, Struggled with #8 for about half an hour from the bottom, then decided to take the O2 sensor out and that made a world of difference. Being 6'2" and 270 probably isn't the best for trying to squeeze my hand back there

Driver's side was done in 15 min.
The stock plugs (63K miles) gap had eroded away to .070. I had a little bit of a rough idle that is now gone. It also cured a bad low rpm freeway stumble, so now 6th gear is usable again.
Well worth the $18 for the TR55s.
